Custom Software & Apps
for Dropshipping & DTC Operators
You're spending $4k/mo on Shopify apps that each do 30% of what you need. You're picking ad creative blind because iOS 14.5 ate your attribution. Your supplier just raised prices and you have no way to A/B route to the backup. Katie builds the custom layer that fixes all three.
Who this is for
- Dropshipping operators running 2+ supplier sources (CJ · Spocket · AliExpress · US 3PL)
- DTC founders at $1M-$20M GMV bleeding margin on app subscriptions
- Anyone whose Meta ROAS dropped after iOS 14.5 and never fully recovered
- Brands ready to graduate from "everything via Shopify app" to "owned data infrastructure"
What Katie ships
🚚 Multi-supplier order routing
Auto-pick cheapest in-stock SKU at order time across CJ · Spocket · custom 3PL APIs. Margin recovery starts the day it goes live.
📈 Ad-CAC attribution that survives iOS 14.5
Server-side conversion tracking + custom event matching · creative-level CAC visible again. Stop guessing which ad is profitable.
🧪 AOV experimentation engine
Custom upsell · cross-sell · bundle logic at checkout. Not a $99/mo app — your own logic, your own variants.
📊 Margin dashboard
Per-SKU profit after ad spend · supplier cost · shipping · returns. The number you actually run the business on.
